Microsoft is aware of an issue after installing the Windows 10 October 2018 update (version 1809) that prevents Microsoft Store apps from connecting to the Internet on devices that have disabled IPv6.
Microsoft is working on a solution that is planned to be released in a future Windows update.
In the meantime, you can resolve this problem by enabling IPv6:
- Open the Settingsapp and select Networking & Internet >
Network and Sharing Center.
- Select the network adapter you're using (by clicking the appropriate link next to “Connections”) and select Properties.
- On the Networking tab, select the checkbox next to Internet Version 6 (TCP/IPv6).
- Select OK to save your changes.
I just checked and IPv6 is enabled by default ( checked ) and also shows a IPv6 mac. I still cant see any games in the windows store app, play Forza Horizon 4 ( it loads the splash screen and crashes to desktop ), and i didnt install any 3rd party Internet
security software. I did an upgrade ( not a clean install ), the win 10 version in settings is 17763.1 Installed on 10/3/2018.
Just saw Pedros post and Network profile was set to Public by default.
Everything ( win store and Forza Horizon 4 ) was working fine until an hour ago, i shut down my computer and it showed a windows update screen when shutting down. Now Store and Forza is broke.
Also why does windows need IPv6 when our Internet service provider doesnt have IPv6 yet ?
